Discussion Overview

The discussion centers around the current status and progress of fusion technology in 2021, exploring various methods of energy generation through fusion, including laser and magnetic confinement techniques, as well as the potential use of helium-3. Participants express concerns about the reliability of information available and the funding dynamics affecting research and development in this field.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant expresses difficulty in finding reliable sources of information on fusion technology's progress in 2021, citing issues with outdated or sensationalized news.
  • Another participant suggests caution when using the internet for research and provides a link to a journal, which is later challenged by another participant as irrelevant.
  • Several links to articles about fusion technology are shared, but their relevance and authenticity are debated among participants.
  • One participant reflects on historical claims about fusion being "just a few decades away," suggesting that funding could have been better allocated to proven sustainable technologies instead.
  • Another participant counters that proven sustainable technologies receive significantly more funding than fusion research, arguing that reduced funding has delayed progress in fusion technology.
  • A claim is made that the budget for fusion research has remained constant since its inception, with a notable reduction only during the 2008 financial crisis, which some argue has led to a lack of results.
  • Another participant argues that adequate funding is necessary for developing full-scale reactors, noting that the costs associated with ITER are relatively low compared to other energy technologies.

Areas of Agreement / Disagreement

Participants express differing views on the funding and progress of fusion technology, with some arguing that funding has been insufficient while others claim it has remained constant. There is no consensus on the effectiveness of current funding levels or the future of fusion technology.

Contextual Notes

Participants reference various sources and historical perspectives, highlighting the complexity of funding dynamics and the challenges in achieving significant advancements in fusion technology. The discussion reflects uncertainty regarding the current state of research and the implications of funding on future developments.

I am having difficulty finding reliable sources of news and information regarding the status of various methods of attempting to generate energy through fusion, but unfortunately, the information is either outdated, is nothing but rumour and conjecture, or has been... how shall I put it... "coloured" by attention seeking media.

I want to know how fusion technology is doing this year with it's various means (laser, magnetic chamber, helium-3 etc.), any reliable information you could share regarding its progress?
 
Engineering news on Phys.org
when it comes to something like internet ... the websites are only to get you to them not often to provide things what you want..
so you must use the internet with caution ..
maybe you like this one

That link you provided has nothing to do with fusion!
 
 
Ah, yes, same old same old, they said its just a few decades away back in the 70's. The whole thing is a cash hole that could have been better spent for implementation of already proven sustainable technologies.
 
All those proven sustainable technologies get much more money than fusion research.
Fusion power plants today might have been possible if funding for fusion went on as expected a few decades ago. If you cut funding, you delay research, that's not magic.
 
Fusion technologies budget has remained more or less constant since preliminary studies have began, they even adjusted them for inflation rates... they had all the money they had since the beginning... that is until 2008 and the financial crysis, but that was over 30 years ago. The reduced budged remained since the financial crisis because for all that time, they failed to produce results.

Right now, the most efficient fusion reactor has China, with 27%, but even that could be commercial boasting!
 
You can't develop a full-scale reactor with funding sufficient for preliminary studies. I said "as expected", not "constant".

By the way, the ITER costs, even if they go up a bit more, are something like 60 (US-)cents per citizen and year. Compare that to roughly $100 per citizen per year for photovoltaics in Germany (don't have US-numbers there, they are probably lower).
